A backup for most of the date is there, but not for the latest ones. :-( The crash occurred during a download (system hangs totaly, hard reset) with a Fedora 3.5.2 linux kernel. The btrfs partition was working quite good for about one year. here is a try to attach the device and mount manually: ----------------------------------------------------- [ 3123.582387] sd 1:0:0:0:
